Description

A non-combustion tobacco smoking device based on PTC ceramic heating

technical field

The utility model relates to an appliance used in the field of heating non-combustion tobacco, in particular to a non-combustion tobacco suction device based on PTC ceramic heating. the

Background technique

PTC ceramic heating is a common heating method in industry and people's daily life. Constant temperature heating PTC thermistor has constant temperature heating characteristics. The surface temperature of the PTC thermistor will maintain a constant value, which is only related to the Curie temperature of the PTC thermistor and the applied voltage, but has nothing to do with the ambient temperature. the

PTC heater is a heating device designed by using constant temperature heating PTC thermistor constant temperature heating characteristics. In small and medium power heating occasions, PTC heater has constant temperature heating, no open flame, high heat conversion rate, minimal influence by power supply voltage, and long natural life. Incomparable advantages such as traditional heating elements, the application in electric heating appliances is more and more favored by R&D engineers. the

With the continuous deepening of the global tobacco control campaign, the research and development of new tobacco products has been paid more and more attention. Various new tobacco products, such as bagged mouth tobacco products, chewing tobacco and snuff, have been launched and have occupied a certain market share. The biggest advantage of the product is that it will not burn with an open flame during use, will not produce "second-hand smoke" hazards, and will not have hidden dangers such as fire. However, based on the long-term consumption habits of smokers, they still have a soft spot for the conventional smoking methods of tobacco. Therefore, a tobacco that can not only meet people's smoking consumption habits, but also avoid open flames caused by tobacco burning and reduce the harm of "second-hand smoke" The suction device has attracted the attention of researchers in the industry. A Chinese patent discloses a "blending additive for atomizing tobacco smoke after heating, its use method and tobacco composition", the patent application number is 201210267881.4, which discloses a tobacco heater, which is placed in an oven The electric heating sheet heats the tobacco and blends additives, and then smokes and enjoys the tobacco. Its tobacco heating method is heating by electric heaters, and its heater structure is relatively complicated, and no other heating methods are mentioned. The patents "Electric Smoking System and Cigarettes for Delivering Cigarettes and Cigarettes" (Patent No. 94102530.6) and "Heater Used in Electric Smoking Appliances and Its Manufacturing Method" (Patent No. 95190277.6) applied by Philip Morris in China also use electric heating. Way. the

Contents of the invention

The purpose of this utility model is a non-combustion tobacco suction device based on PTC ceramic heating designed based on the above-mentioned existing technical conditions. A non-combustible smoking appliance catering to market demands. the

The purpose of this utility model is to adopt the following technical solutions: a non-combustion tobacco suction device based on PTC ceramic heating, including a shell, a PTC ceramic arranged along the side wall of the shell, and a power supply arranged at the rear of the shell, in the center of the PTC ceramic There is a tobacco heating cavity in the part, and an airflow channel is left between the power supply and the casing, and a fan and an airflow control element are arranged between the power supply and the tobacco heating cavity, and the heating of the tobacco heating cavity and the rotation of the fan are simultaneously controlled by the airflow control element (airflow control The element can control the heating of the tobacco heating cavity by the power supply through the suction airflow, that is, when the power supply is turned on during suction, the ceramics will be heated and the fan will be turned on; The front end of the heating chamber is provided with a mesh plate between the filter tip and the tobacco heating chamber, and an air intake mesh is also provided at the bottom of the casing. the

In the invention, the power control component is a battery or a converter connected with external electricity. The heating temperature in the tobacco heating chamber is 100-500°C, and the heating objects are different forms of tobacco materials such as tobacco leaves, tobacco flakes, and tobacco extracts. the

A filter sheet is added in the filter tip, and the filter tip and the shell of the tobacco heating cavity are connected by thread or inserted, so the combination is very convenient. the

When the utility model is used, different forms of tobacco materials such as tobacco leaves, tobacco flakes, and tobacco extracts are used. Put it into the tobacco heating cavity, control the heating through the airflow control element (that is, the pneumatic switch) and transport it through the fan, and the generated volatiles enter the oral cavity through the filter tip, so that the smoker can feel satisfied. the

The biggest feature of the utility model is: constant temperature heating without open flame, energy saving, high efficiency and no pollution, which not only conforms to people's smoking consumption habits, but also can avoid open flames caused by tobacco burning, environmental protection and pollution-free, and can reduce the harm of "second-hand smoke", which has potential market competition force. the
